- Don't close your browser nor reaload the page during your training - you will lose all training data. - Stopwatch GPS requires Internet connection only at the beginning of your training (to load the page) and right after it (essential to send data). During your trining you need Internet connection only to load course map. - Stopwatch GPS bases on phone browser geolocation. You should allow to get location (Always allow). - If you cannot get GPS signal, try to configure GPS settings on your phone, e.g.: Settings -> Location & security -> Use wireless networks - off, Use GPS satellites - on. - RunCalc may be inactive when your phone is locked. Don't lock your phone and disable auto locking. On Android you can do it like that: Settings -> Display -> Screen timeout -> 30 minutes. Using armband with unlocked phone inside is strongly recommended. - Autolap parameter tells RunCalc how often (in distance intervals) it should register laps. There's a limit of 150 laps, so if you set 20 m, your course will be measured precisely up to 20 * 150 = 3000 m. If you plan a longer course, you should set longer autolap. - Correction option allows RunCalc to eliminate invalid locations given by GPS, which makes distance measurement more precise (useful on some phones with inaccurate GPS module). - Remember to send your data to portal after finishing training. You can also set up sending data after each lap automatically ("Send laps" option). - As of Chrome 50 web geolocation API doesn't work - please use other browsers.
